かけるようにしていた。2. Description of the Related Art A conventional fully automatic washing machine is shown in FIGS.
As shown in (1), the washing and dewatering tub 1 has a pulsator 2 rotatably disposed at the center bottom. Water tank 3 is a washing and dewatering tank 1
And a substrate 4 is fixed to the outer bottom of the water tank 3,
A driving motor 5, a drain valve 6, a washing / dehydrating switching mechanism 7 equipped with a brake, and the like are provided. The outer edge of the substrate 4 is connected to the upper corner of an outer frame 10 via a vibration isolator 8 and a hanging rod 9. Hanging support from the corner. Provide an upper cover 11 on the upper part of the outer frame 10,
A water supply valve 12, a power switch 13, a control device 14, and the like are provided. The control device 14 includes a signal control means 15 composed of a microcomputer, an operation display means 17 composed of a key switch and a display device provided in an operation panel 16, and a motor 5, a drain valve 6 based on a signal from the signal control means 15. , A signal from a safety switch 19 and a signal from a rotation detecting means 20 for detecting the number of rotations of the motor 5 are input to the signal control means 15. . 21 is an AC power supply, 22
Is a phase advance condenser of the motor 5. Signal control means 15
Turns on the drain valve 6 in the first drain state in the dehydration process
In this state, the water in the washing and dewatering tub 1 is drained, and after this draining is completed, the motor 5 is turned on. Thereafter, the motor 5 is turned on and off at intervals of several seconds to perform an intermittent operation, and the water of the clothes is gradually drained. In this case, the number of rotations of the motor 5 is detected by the rotation detecting means 20 each time and input to the signal control means 15. Thereafter, the motor 5 is kept ON to perform a continuous dehydration operation, and after the clothes are dehydrated, only the motor 5 is turned OFF and the washing and dewatering tub 1 is operated by inertia. 6 is turned off and the brake is applied to end the spin-drying process. Generally, in a fully automatic washing machine, washing and draining are performed, and then the process proceeds to a dehydration process. At this time, clothes are rarely evenly distributed inside the washing and dewatering tub 1 and have a non-uniform distribution. The dewatering action is performed as it is, and the unevenness of the clothes causes an imbalance of the rotating object and causes vibration. Now, the configuration supported by the vibration isolation system such as the hanging rod 9 and the vibration isolation device 8 is called a vibration system, and one that is inevitably constituted by the vibration system and the vibration isolation system is a natural frequency. If, at the time of dehydration, when the unbalance of the cloth is large, the frequency generated in the vibration system and the natural frequency match, if the amplitude of the vibration system becomes extremely large, for example, jumps up and down, A state called a normal resonance point occurs where the outer frame 10 collides or the rotating shaft is damaged at a critical speed. In order to prevent such a phenomenon, when the amplitude of the vibration system is abnormally large, the power to the motor 5 and the drain valve 6 is turned off by the safety switch 19 as shown in the stroke diagram of FIG. Release the driving force and apply the brake to the washing and dewatering tub 1 immediately.
Was stopped so that there was no danger. However, when the safety switch 19 is operated to release the driving force to the washing and spin-drying tub 1 as described above, and the brake is applied to immediately stop the washing and spin-drying tub 1, safety is ensured. However, there was a problem that the vibration system collided with the outer frame 10 and the collision sound and the movement of the outer frame 10 were generated. Therefore, as shown in the stroke diagram of FIG. By stopping the power supply to the drain valve 6 after the delay time t has elapsed, the driving force to the washing and spin-drying tub 1 is released, and the brake is applied a short time after the inertia rotation.
